Drawdown constrained

filtered admission · selection entries 27 Sep–3 Oct 2026 UTC · source cutoff 4 Oct 06:00 UTC

Research only

Drawdown constrained was infeasible under its preregistered selection constraint. The interactive controls open on the incumbent for exploration; there is no frozen approach roster. The filtered arm requires a historical v1 h60 CLEAN score available at entry and vetoes causal BUNDLED scores. Raw means no additional 335 gate; the frozen RH universe already had safety gates. The pre-window is held out from this re-selection but overlaps earlier model development. The post-window has at most one complete entry hour and is underpowered. Scorer coverage is in the report.

Composer controls

Fee 0 as in the frozen RH composer; impact, participation, token caps and joint settlement use its published engine. Changing controls is exploratory and does not change the frozen tables.
